Cystathionine β-synthase (CBS), CSE (cystathionine γ-lyase) and 3-mercaptopyruvate sulfurtransferase (3-MST) have emerged as three significant sources of hydrogen sulfide (H2S) in various forms mammalian cancer. Here, we investigated the functional role CBS’ 3-MST’s catalytic activity murine breast cancer cell line EO771. The CBS/CSE inhibitor aminooxyacetic acid (AOAA) 3-MST 2-[(4-hydroxy-6-methylpyrimidin-2-yl)sulfanyl]-1-(naphthalen-1-yl)ethan-1-one (HMPSNE) were used to assess endogenous H2S modulation proliferation, migration, bioenergetics viability vitro. Methods included measurements (MTT LDH assays), proliferation vitro wound healing (IncuCyte) cellular (Seahorse extracellular flux analysis). CBS 3-MST, well expression detected by Western blotting; production was measured fluorescent dye AzMC. results show that EO771 cells express CBS, protein, several enzymes involved degradation (SQR, TST, ETHE1). Pharmacological inhibition or inhibited production, suppressed attenuated proliferation. Cell migration only inhibitor, but not inhibitor. Inhibition did significantly affect basal viability; (but CBS/CSE) slightly enhanced cytotoxic effects oxidative stress (hydrogen peroxide challenge). From these findings, conclude H2S, generated a lower degree CBS/CSE, contributes maintenance bioenergetics, may also exert minor cytoprotectant.

Abstract Background Hydrogen sulfide (H 2 S) is a significant endogenous mediator that has been implicated in the progression of various forms cancer including breast (BC). Cystathionine-β-synthase (CBS), cystathionine-γ-lyase (CSE), and 3-mercaptopyruvate sulfurtransferase (3MST) are three principal mammalian enzymes responsible for H S production. Overexpression CBS, CSE 3MST was found to be associated with poor prognosis BC patients. Moreover, linked an immune-suppressive tumor microenvironment BC. Recently it observed cells, response single or dual inhibition synthesizing enzymes, develop escape mechanism by overexpressing alternative sources generation. Thus, aim this work compensatory pan repressing using microRNAs (miRNAs) investigate their impact on oncogenic immunogenic profile cells. Methods female patients ( n = 25) were recruited.

Atherosclerosis is a chronic inflammatory condition marked by endothelial dysfunction, lipid accumulation, cell infiltration, and extracellular matrix (ECM) remodeling within arterial walls, leading to plaque formation potential cardiovascular events. Key players in ECM inflammation are metalloproteinases (MMPs) CD147/EMMPRIN, surface glycoprotein expressed on cells, vascular smooth muscle cells (VSMCs), immune that regulates MMP activity. Hydrogen sulfide (H₂S), gaseous signaling molecule, has emerged as significant modulator of these processes including oxidative stress mitigation, reduction, remodeling. This systematic review investigates the mechanistic pathways through which H₂S influences MMPs CD147/EMMPRIN assesses its impact atherosclerosis progression. A comprehensive literature search was conducted across PubMed, Scopus, Web Science databases, focusing studies examining modulation contexts.
